DRILSDOWN Case Study: Equatorial "moisture island" budget in MERRA2
Notebook of IDV visualization session
Case dates: 2007-08 13th to 17th
Drilling down into the science of:
Mapes, Cheedela, Igel, Tsai 2019: The dynamics of water vapor islands over the western equatorial Indian ocean. In preparation

The following shows CWV and IR cloudiness for a moisture island in the WEIO:¶
In [7]:
%make_image -capture legend -caption "An equatorial moisture island, convecting where CWV > 50mm or so"
In [24]:
%make_movie -capture legend -caption "Vapor is well behaved in time, although convection flickers"
The following shows dqvdt_mst on -10 t0 10 mm/d scale (red = drying)¶
In [9]:
%make_image -capture legend -caption "Moist physics is a vapor sink (precipitation)"
In [12]:
%make_image -capture legend -caption "Evaporation I take it, -10 to 10 mm/d color range"
The following shows total physics (E-P): mst is the sink (red), trb is the source (blue)¶
In [11]:
%make_image -capture legend -caption "Total physical tendencies"
In [19]:
%make_image -capture legend -caption "Smoothed physical tendencies"
The following shows dqvdt_dyn -- moisture convergence/ vertical advection so big noisy!¶
In [14]:
%make_image -capture legend -caption "DYN source, wildly saturates -10 to 10 mm/d color scale !?"
Dynamics dqvdt_dyn -- still big even when smoothed, and big all over¶
In [15]:
%make_image -capture legend -caption "DYN source, wildly saturates -10 to 10 mm/d color scale !?"
DYN+PHY pattern looks almost totally like DYN, albeit weaker a bit¶
In [25]:
%make_image -capture legend -caption "DYN+PHY"
That leads us to dqvdt_ana -- Analysis Tendency¶
In [16]:
%make_image -capture legend -caption "ANA tendency term "
ANA term smoothed¶
In [18]:
%make_image -capture legend -caption "ANA term smoothed"
Well, DYN + PHY + ANA does add up to the time tendency¶
In [29]:
%make_image -capture legend -caption "DYN + PHY + ANA"
In [28]:
%make_image -capture legend -caption "Time tendency over 3 hours"
In [30]:
%make_movie -capture legend -caption "Analysis tendency"
